wuerden eine u To all whom it :may concern:

Be it known that. I, O'ri'o KA'rrnNHouN, a citizen of thejlUnited States, residing at Battle Mountain, in the county of Lender and State of Nevada, have invented certain new and useful Improvements in Airship- Propellers, of which the following is a speciication.

This invent-ion relates to air ships, und more particularly to means for propelling the same, and has for its object to provide a means for controlling' the transverse contour of the under surface of pivoted wings operating on the same principle as the wings of birds.

Another object of the invention is to provide a means for flexing, or bending a vane ofthe kind mentioned to present u concave surfacin the direction of its movement during esclu stroke..- i

' f n importent object is to provide e means f governing the relative movement be tween the dil-ferent parts of the wing 1pngitudinlly thereof, so that at the time 0.-." a stroke f. e surface of the wings will be `inclined rongitudinally in such a direction as to give a' forward impulse both on the upward /and downward stroke of the wings, :1s

well as to Igive a lifting impulse on each downward stroke.

Another object of the invention is the pro- Vision of a novel means for giving pivotal movement to a. wing.

Another object is to provide a novel form .of operating mechanism for inducing diiierent degrees of movement in different portions of a wing laterally thereof.

Other objects and' advantages will be ep parent from the following description, and

1t will be understood that4 changes in the specific structure shown and described may be made within the scope of the claims with-r out departing from theA spirit lof the invention.

In the drawin forming a porti'nxof this specification, an in which like numerals of reference indicate similar parts in the several views, Figure 1 is a top plan view of a skeleton frame of an air ship equipped with the present invention, Fig. 2 is e ront View thereof, Fig. 3 is a side view, Fig. 1 is a y detail front view "of one Wing and the operating connections therefor, with the device on a downward stroke, Fig. 5 is u. similar view showing the device on lthe upward stroke, Fig. 6 is an end View of the driving speunmmfmemmwa Patented Aug. 22, 1911.

shaft, Fig. 7 is aperspcctive view of one end of the crank shaft, Fig. 8 is a detail sectional view of the mounting ,for the'wings and operating" cross arms, Fig. 9 is a firegmentury view of a propelling mechanism in which the driving means is modified.

Referring to the drawings, there is shown a frame A comprising the' longitudinally extending side beams 10, which. are tapered ut their opposite extremities as shown at 1l, and carry the blade-like cross pieces 12 connected between their ends. ,Transverse beams 13 ure carried between the members 10, upon which is suitably journaled the drive shaft 13. A suit-able motor of :my type as indicated at C muy be mounted upon the frame, and connections mede between this and the shaft 13. Secured to the outer sides 4of the members' 10, there are longitudinally spaced brackets 15, each comprising en approximatclyU-shuped body portion, havin the extremities of its opposite arms extend laterally as at 16 to provide securing por-v 'rectangular framework including the lateral arms 19 which ure gradually tapered toward their outer ends, and the longltudinal struts 22 coenguged between their oppo site extremities. The lateral members 19 are of flexible nmterial and connected to their extremities and extending from opposite sides, there ure cable members 23 conlnected to the extremities of the cross arms 21 at the adjacent sides of the freine, the upper cable being extended downwardly through the body of the machine, and the ylower one being extended upwardly, each rbeing connected to the respective ends of the cross erm 21 at the opposite side of' the machine, from which point they are carried to the extremities of the adjacent lateral arms 19' und secured shown. The cables thus intersect euch other centrally of the frame, and hold the opposite wings rigidly sides of the lateral members 19, there are 'lo similarly to the arms 20 upon the opposite vided with crank portions 25 and 25 disv ranged to move in a widerradins than the set with respect to the anis of the shaft, and

a direction indicated by the arrow in Fig. 9.,

.3@ 23 moving in a greater are give a greater .thereoi and the crank portions 26 connected itothe cables 24 being spaced inwardly of 3b' the cranks 25, and rearwardly thereof, the

'40 that they are always concaved in the direcof cranksloeingset at an angle of sosie l5 tion of the rear portions of the vines occ 59 lward the front, and on the upward stroke.

i presented of the rived from the op eration. of the device,

60* used on 5 mediate crank portion l? connected. to a cen- 'In their relative positions with respect to l ne horizontal and making 'their movement synchronous in a common direction.

Secured intermediatcly to the opposite cables 24; extending inwardly and heingsecured to the respective extremities of the cross arms 20, and being carried parallet'o the first mentioned cables `and connected side orf the frame, from whence they are extended Vto the intermediate portions of the lateral members 19.

lt will loe noted that the shaft l proposed respectively in the plane of the cables 23 and 2li. There is one of 'these sets "of cranlrs at each: end of the shaft, and it will loe noted that the crank portion 25 is arcranlr- 2G which is spaced from the radius of thelcranlr 2 a distance of approximately thirty degrees. The forward set of cranks is advanced. sixty degrees beyond the rear the direction ci? movement thereoit'. Thus in operation, when the shaft 13 1s rotated 1n the crank portions 25 connected to the cables degree of movement to 'the end portions of the wings, than the intermediate portions somewhat later than the movement of' 'f forward ends, so that on. the downward stroke the outer portions of the wings wil be inclined downwardly from the rear' to will he inclined upwardly from the. rear 'ton ward the front of the machine. A. forward impulse is thus given to the'm'achine, and loy reason oif'the concavity ofthe surfaces against 'the air during the ystroloe wings, the maximum eiiciency is def tshould he observed that by the form o'l' lconnections provided but one shaft need be small machines but in. Fig. 9 there is illustrated a modified form of the device in which two shafts are utilised, which may he found desirable in. machines or large size9 and in addition there is illustrated an inter- Leonesa tral set of cross pieces and lateral members similar to those at the forward and rear ends of thewings. It vwill be noted that the :intermediate set of cran'ks are spaced intermediately of the forward and rear sets with respect to the periphery of the crank shaft, so that the longitudinal inclination of the wings will be properly sustained..

. lt will loe apparent from the foregoing" that the number of lateral members and crane. operatinglfnirtionsl may be multiplied as much as desirable, and the spacing of the cranks radially of the shaft' and peripherally thereofv may be varied. as found desirable it will loe also understood that any desirable construction. of iframe may be kutilized vfor the support ot" the 'device Ato adapt the device 'or use upon various types of machines.
